Abstract
La presente invenzione si basa su un procedimento per la rimozione degli effluenti dai gas di scarico generati dalla combustione di un combustibile idrocarburo e, più in particolare, un procedimento come sopra specificato in cui si inietta un nitrato assorbente degli effluenti nel flusso dei gas di scarico a valle della zona di combustione ad una temperatura controllata del flusso dei gas di scarico.
